If you add up the percentage falls in UK real pay for each later year, taking 2008 as the base for calculation, you reach an overall loss over 7 years of 38.5% of the 2008 wage (see Table 1 below). This means that a notional worker employed at an average wage in 2008, if employed throughout at the evolving annual average, will have lost over one-third of a year’s salary (in real terms) compared to her 2008 pay. Or roughly £10,000 in total. And that would just be to stand still in terms of pay….

True, the headline UK employment and unemployment figures for the 3 months to November paint another positive picture. The number of those aged 16 to 64 in employment rose by 213,000 over the previous (June-August) months, and including those 65 or older, the increase was 267,000.

But as we know, there is a darker side to the picture – the gain in employment is a trade-off in terms of pay. The gain in employment is closely matched by the fall in pay, as Table 1 below shows. In 2014 the number in employment was up 4.1% on 2008 – but real pay was down by double the rate, at 8%. In 2015, the increase in employment is just about equal to the fall in pay.

Let’s stick with the positive for the moment. The year-on-year increase in those in some form of employment is 589,000, while the 16-64 population (the potential workforce) is estimated by ONS to have risen over the year by only 100,000 (though this seems curiously low – the population aged 16+ is estimated to have risen by 325,000). Unemployment for those aged16+ has fallen in the year by 239,000 to 1.656 million.

Over the last Quarter (to November), there were 160,000 more employees, and 121,000 more self-employed. So the self-employed are again a big proportion of the total.

There were 110,000 more full-time employees, and 50,000 more part-timers than in the previous 3 months. There were also 84,000 more full-time self-employed, and 37,000 more part-time self-employed. So some of the gain is in part-timers and a fair proportion in self-employed, but over one-third is in full-time employees.

It’s time to turn to pay (and n.b. the ONS data for wages applies to employees, not to the self-employed, so the overall picture is probably worse). For another month, regular and total pay rose annually by more than CPI inflation (currently 0.2%) but not by a big margin. And as yet, nowhere near enough to compensate for the huge fall in real pay since 2007/08.

Total pay in November rose by 2%, the same annual rise as for the last 3 months’ average. Regular pay (excluding bonuses) was up 2.1% in November, 1.9% averaged over the 3 months. Two service sectors saw significant annual increases – construction workers (+5.6% total pay) and those in retailing/hotels/restaurants (+3.2%).

In order to see how the trade-off between the number of those in employment (of whatever kind) and levels of pay (of employees) has worked, in Table 1 we have taken data from 2008 (as base 100) and show the annual percentage changes from that baseline. To give the context of the overall economy, we have included the GDP figures (also calculated as the annual % change over 2008 level).

Sources: all from ONS datasets as at 20th January 2015Real GDP is annual GDP data, with estimate for Q4 of 2015 includedNumber in employment and hours worked use September-November data per yearTotal and regular real pay use annual data; for 2015, index of 112.5 is used for total pay, and 111.3 for regular pay.

It will be seen for the Table that following the great financial crisis, in 2009 and 2010, there was some broad relationship between the numbers in employment, the hours worked, and the level of total pay (regular pay fell only slightly at first). From 2011 on, that relationship totally broke down. Real GDP was still slightly below 2008 level, as were the numbers in employment (of whatever form) and the hours worked. But real pay (the difference between nominal wages and inflation) collapsed, and fell further and deeper in 2012, 2013 and 2014 – so that total annual pay in 2014 was a huge 8% below the 2008 level.

In 2014, we note further that the rate of increase in employment since 2008 was 4%, or half the rate by which real wages had still fallen (8%). Because real pay - to a limited extent - improved in 2015, there seems to be, for that year, an almost perfect correlation or trade-off between the rate of increase in employment (+6%) and the rate of fall in total pay (-5.7%), relative to 2008.

Moreover, the figures set out above for real pay do not represent the full extent of the fall since the peak in 2008 – comparing November 2015 with February 2008, the fall in real total pay is still 10%, and comparing Q3 2015 with Q1 2008, the drop was 7.8%. (The largest month to month fall, in 2014, was over 12%).

Of course, the figures do not mean that in every sector of every industry there has been a large cut in real pay – it also indicates that since 2011, our economy has shifted to a lower pay economy as a whole, with a substantial proportion of new jobs (employed or self-employed) in lower-paid sectors.

The comparison of GDP and hours worked, over these years since 2008, also point up the fall in labour productivity (and see here), which is inevitable with a shift to a lower real wage economy.

There are of course other advantages in more people being in employment. But thus far, it’s been a simple trade-off. More people working to produce not much more stuff at much reduced pay. I remember saying that back in 2012!

Finally, here is another version of the chart at the head of this piece. It is a bar chart, which is perhaps more appropriate for the task... but I can't help feeling the scissors effect on the first version tells the tale most clearly and truly!
